Hi,

I am having trouble with using fMRIpost-AROMA. My sequence has TR that is longer than 1.0 sec, and fMRIpost-AROMA sets it to 1.0 and I can’t run GLM or other analyses due to the timing mismatch results from this. What can I do? Thank you in advance.

For now, I am adding this quick fix after running AROMA

  for run in ${RUNS}; do
    fslcpgeom \
      ${FMRIPREP_DIR}/sub-${PNUM}/func/sub-${PNUM}_task-${TASK}_run-${run}_space-MNI152NLin6Asym_res-2_desc-preproc_bold.nii.gz \
      ${AROMA_DIR}/sub-${PNUM}/func/sub-${PNUM}_task-${TASK}_run-${run}_space-MNI152NLin6Asym_res-2_desc-nonaggrDenoised_bold.nii.gz
  done

That looks like a bug in fMRIPost-AROMA. I’ve opened an issue (TR is not set in denoised BOLD files · Issue #119 · nipreps/fmripost-aroma · GitHub) and I’ll try to fix it for the next release. Thanks for reporting!

Sounds great, I look forward to the update. Thank you for a great software.

Can you try the updated nipreps/fmripost-aroma:main Docker image and see if the TR is correct now?
